' LIQUlb MEASURIfiG DEVICE.

Specification of Letters latent.

Patented May 4, 1 909.

To all whom *itmay concern:

Be it known that we, HARRY ADELsoN and CLARK W. BLIss, citizens of the United States, residing at Cleveland and Lakewood, respectively, in the county of Cuyahoga and tate of Ohio,have invented certain new and useful Improvements in Liquid-Measuring Devices; and We do declare that the folloz: ing is a full, clear, and exact description of the invention, which v. ill enableothers skilled in.

the art to which it appertainsgtoniake and use the same. I

a Our invention relates to liquid measuring devices, and the 'inventionis embodied in a division of our application for Letters Patent dated AugustlO, 1907, Ser. No. 387,959..

In the accompanying drawings, Figure 1 is a side elevation of a liquid measuring apparatus comprising our invention within the same, and Fig. 2 is a vertical sectional elevation of one of the measuring units or receptacles employedin said apparatus and considerably enlarged. Fig. 3 is across section on line 33, Fig. 2, looking dotvn.

The invention as thus illustrated covers substantially the same construction as is shown in Fig. 7 in the above entitled application but isnot specifically claimed therein, another construction of valve mechanism being specifically claimed in said case. The

present invention is, therefore, confined more particularly to the parts arranged and adapted to operate substantially as shown .and comprises a vessel or receptacle V, one or more, and usually a series of such vessels are employed and operatedtogetherin tank T an operatively connected with cover O, or equivalent part, free upon saiditank to be raised and lowered. For this purpose, as in said other application, We employ opposite side frames F, which carry cover 0 and are raised and lowered by toggle links L, connecting piece P and handle or lever H. The foregoing or other operating mechanism may be employed for the valve controlling sleeve S and rod R and associated mechanism, the sleeve S bearing against part 0 from beneath and rod R extending through part 0 and having adjusting nuts 2 on its upper end adapted to give more or less play to said part or cover C before it engages said nuts and raisesvalve 3, which is fixed to the lower end of saidrod. Neither rod It nor sleeve S is fixed to cover C, and sleeve S is sustained against the bottom of part O by spring l'beneaththe same about rod R and bearing at its lower portion on ball valve 3. A suitable guide 5 on sleeve S supports said sleeve in a central position in vessel V...

The valve 3 controls the exhaust or outlet from the measuring vessel, and ball valve 6 controls the inlet or supply opening 7 for liquid to fill said vessel from the interior of tank T.. The said ball or valve 6. is free in a cage to rise and fall as to seat 7, which is in the top of a side extension 8 formed integral with vessel V, in this instance, and constituting a part of the measuring space of the vessel. An arm or lever 9 is pivoted between its ends in said side extension or space and has an upwardly extending end adapted to engage beneath ball 6 and raise the ball from its seat to. admit liquid into the vessel, and said lever is bifurcated at its other end and engaged about rod It and spring 4 directly beneath the flange d at the lower end of sleeve S. It follows that when cover 0 is lowered it will depress sleeve S against its sustaining spring 4 and bearing upon the end of lever 9 v.-ill raise valve 6, but not before valve 3 has been depressed to its seat 1.0, as hereinafter more fully described. Vessel V has an externally threaded extension 12 at its bottom Which seats snugly in a corresponding openingin the bottom of tank T and said extension is engaged by a ring nut 14 about its side next beneath said bottom, thus firmly fixing the said vessel in said tank with its valve seat 10 outside and beneath the tank. I

In operation the positions of the valves 3 and 6 are determined bythe position of cover 0 through lever H and intermediate parts controlling saidcover, and the measuring I Fig. 2 and valve 3 is closed and valve 6 open.

Then When the said vessel has been discharged the cover C is correspondingly raised and valve 3 opened and valve 6 closed. But there is enough play in rod R over the cover and beneath nuts 2 to permit sleeve S to rise and valve 6 to seat before valve 3 opens, thus closing off the inflow of fluid While discharging takes place. After the measuring vessel has emptied the positions of the valves are reversed and valve 3 closed before valve 6 opens, and so on alternately. The fluid level in the tank is automatically maintained, as described in the original apl plication, and is the same for all vessels in the tank. Then When the said vessel is to be discharged the cover C is raised against nuts 2 on rod R and outlet valve 3 is opened, but this does not occur before spring 4 has raised sleeve S, as cover C rises and inlet valve is permitted to close through the changed position of lever 9. Thus valve 6 really closes before valve 3 opens though the operation of both valves is a single operation in fact and their seating and unseating or raising is successive and alternate. Valve 3 will in like manner be closed just before valve 6 is opened in a reverse operation of parts, and so on, all the operating parts for all the vessels in tank T working simulta neously.

Valve 6 is preferably provided u ith a stem 20 sleeved through a side supporting arm 22 on vessel V, and a spring 21 arranged between the said arm and valve 6 serves to press and hold the valve to its seat 7 except when raised by lever 9.

What we claim is:

1 A tank adapted to contain liquid, a liquid measuring vessel seated in said tank having an offset at its bottom provided with an inlet opening for liquid to said vessel and an exhaust opening in the bottom of said vessel through the bottom of the tank, valves for said openings and means to open and close said valves in a single operation comprising a rod controlling said exhaust valve, a sleeve on said rod, lever mechanism in operative relation with said sleeve adapted to open said inlet valve, and separate means engaging the upper end of said rod to control said exhaust valve.

2. A liquid measuring tank, a liquid measuring vessel removably seated in the bottom thereof having inlet and exhaust openings at its bottom on different horizontal planes, a separate valve forea'ch opening and means to open and close said valves alternately comprising a rod carrying the exhaust valve and a pivoted lever operatively related at one end with said inlet valve, and means on said rod adapted to operate said lever.

3. A measuring vessel for liquid having an exhaust opening in its bottom and a side extension at its bottom with an opening in its top to admit liquid, a valve for each opening and connections for operating said valves conjointly comprising a rod carrying said exhaust valve and a lever supported in lifting relation to said inlet valve, a sleeve slidably mounted on said rod and engaging said lever and a spring to raise said sleeve, and means at the top of said rod and sleeve to operate both rod and sleeve.

4. The measuring vessel having an exhaust valve seated in the bottom thereof, and a rod on which said valve is mounted, a sleeve about said rod and a spiral spring on the rod between said sleeve and valve, in combination with an inlet valve at one side of and on a plane above said exhaust valve, and a seat therefor, a pivotally supported lever adapted to open said inlet valve and operatively connected with said sleeve, and means at the upper ends of said sleeve and rod to raise and lower the same and thereby control said valves.

5. A measuring vessel for liquid open at its top and ada )ted to be filled to a predetermined level beneath its top and having an exhaust opening directly in its bottom and an inlet opening at its side above the plane of said exhaust, in combination with a valve for each opening and means to operate said valves together comprising a rod carrying each of said valves, a sleeve about said rod, a spiral spring about said rod between said sleeve and said exhaust valve, means between the upper end of said rod and sleeve to raise and lower the same and a lever to operate said inlet valve having working relation with said sleeve.

In testimony whereof we sign this specilication in the presence of two witnesses.
